Pseudo Block Coded Single-Carrier Frequency-Domain Equalization Transmission

In this paper, we propose a pseudo block-coded SC transmission with frequency-domain equalization (FDE). We call this scheme as pseudo block-coded SC with FDE (PBCSC-FDE). A concatenation of block encoding matrix, interleaving matrix, DFT matrix, mapping matrix and channel matrix can be viewed as an equivalent MIMO channel and FDE and block decoding can be jointly performed based on the minimum mean square error (MMSE) criterion. We evaluate, by computer simulation, the average bit error rate (BER) performance of PBCSC-FDE and show that its achievable BER performance is superior to a 2-step decoding which performs FDE and hard decision block decoding separately.
